Magnets and electricity power point
1. Let’s take a FIELD TRIP on the MAGIC SCHOOL BUS! For today’s trip Miss B, will take you through magnets and electricity!
2. SO… What have we learned about magnets that can be useful in our adventure?
3. What do magnets attract? Paperclips? Wood? You are Correct! Glass? Or a flower? Iron nails? Plastic? Other magnets? Pennies?
4. OH NO!!! Our bus broke down! OR What Magnet strength do you think we need to get our bus across this bridge?
5. Magnetic poles Where is our bus headed now? We’re headed to the north, our magnet is pulling to the North pole
6. Magnetic Force Our bus is SO slow, we are never going to get to the North pole in time. BUT… We can make our bus into a big magnet, that way we can use the EARTH’s natural magnetic field to help pull the bus closer to the North Pole!
7. Let’s go into the smallest part of the magnet ATOMS They have protons, neutrons, and electrons
8. Electrons Electrons are attracted to protons, like – is attracted to +. This is how magnets work with each other.
9. Let’s find some natural magnets There are rocks that are magnetic called magnetite, which mother earth makes herself!
10. Now we know about magnets, Where are they used?
11. On Through Electricitiy! Let’s head back home and become electric! Now…. What have we learned about electricity?
12. Electricity It’s a flow of electric charge Positive(+) and negative(-) attractions Just like Magnets
13. Where is electricity used? Let’s flow with electricity that is in lights to learn more!
15. Electric Circuit Oh no! Our bus stopped moving through the circuit! Why? Let’s think of ways to fix it! Yay! We fixed it by connecting the circuit
16. Electricity Discovered! Who is this? Kite with key Benjamin Franklin In 1750, Franklin flew a kite that was hit by lightning
17. Electricity sources. Power from the sun. From the moving water. From batteries. From many different power plants. Power from the wind.
18. WOW! Why is her hair like that? Balloons, when rubbed against something create small static electricity.
19. Try this! Drag your feet with socks on the carpet and quickly touch something like a door knob or a friend. Rubbing a balloon against your head IT’S FUN!
20. WHEW! We made it back just in time for lunch! Remember to share our field trip with your parents. These websites may help! http://www.ehow.com/facts_5895999_science-magnets-kids.html http://idahoptv.org/dialogue4kids/season6/electricity/facts.cfm
